Abstract
An image forming apparatus includes a driving source, a supply roller which supplies a recording sheet, a fixing device, a fixing driving gear mechanism which transmits a driving force of the driving source to the fixing device, a supply driving gear mechanism which transmits the driving force to the supply roller, and a control device. The control device controls the driving source to rotate in one direction when a temperature of the fixing device exceeds a predetermined temperature, and to rotate in a reverse direction when the temperature is the predetermined temperature or lower. The fixing driving gear mechanism includes a mechanism which interrupts a transmission of the driving force when rotating in the reverse direction. The supply driving gear mechanism includes a mechanism which causes a rotating direction of the supply roller to be the same when the driving source rotates in both directions.
